BUCKLE FR STRAPS, BELTS, AND THE LiKE.

Specification of Letters Patent.

Patented Mayl, 1921.

Application tiled August 7, 1918. Serial No. 248,783.

To all w hom t may concern Be it known that ll, Gnnninn ALBERT VALENTIN SoULACnoIX, a citizen of the Republic of F rance, and a resident of 12 Avenue de la Grande Arme, Paris, France,have invented new and useiul lmprovements in Buckles for Straps, Belts, and the like, of which the following is a specifica-tion.

The present invention relates to an improvement in buckles for straps, belts, girths and the like, of the type in which the tongue oi the buckle is mounted on a chassis pivoted on the rear part of the buckle frame, so that by turning this chassis about pivot the point or tree extremity of the tongue can be pulled back or withdrawn until it escapes from the front cross bar of the buckle and the strap be easily freed by means of a' pull exerted thereon.

lin accordance with the present invention, one or more springs supported upon the pivotal axis of the chassis carrying the tongue or prong upon the buckle, acts or act upon this chassis for the purpose of maintaining it normally applied against the buckle framethat is to say with a view to holding the tongue in engagement with one ot the holes of the strap, belt or the like, so, that it is necessary to overcome the tension of the spring or springs in order to be able to open the buckle by turning the chassis about the buckle.

The annexed drawing shows in elevation one 'form oi. carrying out the invention.

The buckle iframe comprises a transverse bar or spindle f1.4 connecting the parallel longitudinal arms a between the rear and front cross-bars a and a2. Upon the rear cross-bar a is stitched or secured in the known manner, one of the ends ot the strap, belt or the like c. Upon the iront cross-bar a? covered by a metal sleeve a3, there rests the point or tree end of the tongue or prong ai; this latter is jointed or pivoted upon a cross-bar b2 connecting the two sides or parallel longitudinal arms b of the prong chassis. These two arms Z) are pivoted at b upon the transverse spindle of of the buckle frame. A spring e supported or bearing on the pivotal spindle a4 of the frame b Z2 b2 and acting upon the cross-bar 292 which car" ries the tongue (Z, maintains the chassis applied normally against the buckle frame by means of curved lateral claws o4 resting on the arms a of the buckle. The tongue d is consequently held forcibly in the hole of the` Vbt, the point of the tongue d slipping upon the front cross-bar a2 of the buckle, is pulled back and escapes from this cross-bar. It is then suiiicient to exert a light pull upon the free end of the strap or the like to free the latter from the buckle.

Naturally, various detail modifications in v the example represented can be made without departing from what l claim as my invention.

l claim- A buckle comprising a frame having longitudinally spaced cross bars, to one of which a strap end is adapted to be permanently secured, and beneath the other of which the free end of the strap is adapted to be passed up between the sides of the trame, a chassis pivoted to said frame at a point located between said cross bars, a tongue on said chassis adapted to pass through said free end of the strap and to overlie the cross bar beneath which the free end of the strap is passed, in combination with spring means engaging said chassis and tending to maintain the tongue in position to overlie said cross bar in strap-engaging position, substantially as described.

ln testimony whereof I have signed my name to this specification.
